    摘要： A transmitter module of a wireless transmission system with at least one transmission path having a power amplifier disposed at the input side includes a low-pass filter disposed at the output side and an impedance converter disposed therebetween. The power amplifier and the low-pass filter are, thereby, disposed on the top surface of a multi-layer carrier substrate. Preferably, the impedance converter is disposed in metallization planes of the carrier substrate. The inventive integration of all of these components in one module especially allows for a step-wise impedance adaptation between the low-impedance amplifier output and the output of the transmitter module having a defined output impedance (e.g. 50 ohm), whereby the impedance adaptation is partially carried out by the low-pass filter. A multistage impedance adaptation allows for a reduction of, e.g., the length of the line sections used in the impedance converter and the signal losses involved.

    摘要： A transmitter module for mobile radio applications includes a multilayer module substrate with levels of metallization and intervening dielectric stacks in which a circuit is implemented by structuring the levels of metallization. In or on the module substrate, at least one HF filter or adjustment network is implemented. On the underside of the module substrate, a cutout, in which a chip element is soldered in a flip-chip-arrangement, is provided. The rear of the chip element pointing to the outside displays a metallization that makes a good thermal contact of the chip element with extrinsic circuit surroundings possible.

    摘要： An X-ray tube includes a vacuum-filled housing and an anode contained in the vacuum-filled housing. The anode is operable to produce an X-ray beam based on electrons emitted from a cathode and attracted by a high voltage applied to the anode. The X-ray tube also includes a high-voltage power line introduced from an external side of the housing for supplying the anode with a high-voltage potential. The X-ray tube includes an electrical feed for electrically insulating the high-voltage power line from the housing. The electrical feed in the X-ray tube includes at least two insulating layers radially between the high-voltage power line and the housing. The at least two insulating layers are separated from one another by a metallic coating.
